- To all whom it may concern:

Belt known that 1, CHARLES S. LABoFIsH, a citizen of the United States, residingat Vvashington, in the District of Columbia, have invented certain new and useful Improvements in Tabulating Devices for T pe- Vriters and I do hereby declare the fol 0wing to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1

My invention relates to improvements in tabulating mechanism for typewriters, and the objects of my invention are, first, to produce a neat, sim 1e and compact tabulating mechanism. fitte to the typewriter in such a manner as to conceal it entirely from view, thereby obviating the usual objections to tabulating attachments which encumber the machine. and detract'from the ap earance thereof; second, to so construct t e tabulating device as to enable the operator to bring a column or columns into vertical alinement by the manipulation of the numbered typewrlter or printing kc s, thereb' dispensing with the auxiliary eys usual y employed to accomplish the results; third, to provide a very sim le and efficient carriagerelease; and fourt to provide easily adjustable and removable column stops which are readily accessible to theoperator To the above and other ends which Wlll hereinafter appear, my invention conslsts of the features of construction, arrangements of arts and combinations of ,devices set fort 1 in the following specification and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a 'vertlcal front to rear sectional view of a typewriter embodying my invention; parts unnecessary to an understanding of my invention be ng omitted from this view. Fig. 2 is a plan view ofa portion of the traveling typewriter carriage. Fig-.3 is a planview with arts broken away showing portions of theta ulating mechanism and the associated parts. Fig. 4 is a detail vertical sectional view taken on the line X X of Fig. 3. Fig. 5is a detail pers ective view of the shift key and combined s ifting and locking device. Figs. 6, 7 8 and 9 are detailed views of the parts entering into the construction of my tabulating device.

Similar letters and figures referto similar parts throughout the several views.

housed; G, designates the numbered typewriter or printing keys; H, a spacing or feed dog; I, the rack, and K, the typewriter scale. The above parts of the typewriter operate in conjunction with my tabulating device, as will be hereinafter described. a

- A rock shaft or sto rod 10 extends inthe direction of-the trave of the carriage and has r a longitudinal groove 11, andis held rotatable in the upperfront portion of the typewriter frame B, close to, and arallel with the rod D, upon'which the rol er E, ,bears. A stop rod 12, T-shaped in its cross section, and having a series of transverse notches 13 cut therein, is rigidly secured in the upper portion of the typewriter frame adjacent to the rod orrock shaft 10, and paral el therewith. A hollow graduated contact piece 15,

is fitted between the lugs F to slide upon the rod 10, and is prevented from turning thereon by a pin 16, which engages the longitudinal groove 11. I The said contact piece consists of .a raised s iral 17 which covers about eight-tenths of t 1e periphery of the sleeve, leaving a space 18 0 about two-tenths bare (for purposes to be hereinafter described) and notches are out upon the said raised spiral so as to form a series of segmentally and spirally arranged steps 19, as shown in Fig. 6 which constitute denominational stops.

Column sto s 20 are iiecessed and shrzped, to fit the T-s a ed stop rod 12 referre to above, and are tted to slide freely thereon. These column stops are each formed with projections 21, extending toward the. spirally arranged stops and with cars 22 to which are hin ed U-shaped'twin cams 23, provided wit a handle 24 wherewith the said cams are operated to engage the notches 13 so as to lock the column stop 20 securely in position at any point on the rod 12,, as clearly shown in Figs. 2 and 7.

A socket 26 is detachably secured to the lower right hand side of the typewriter frame.

tachably held by screws 29 to the lower portion of the typewriter frame just opposite ormed the said socket 26. A rock shaft 30, with rockers 31 and heels 31*, constitutes a frame which is mounted to rock in the bearof the said socket and bracket and has also a slight lateral movement therein against the tension of the spring 32 in the socket 26, as shown in Figs. 3 and 4.

To the rock sh ,ft 30 is secured a crossbar 33 which is in the nature of crank arms that project in opposite directions from the rock shaft and in effect constitute a lever of which the rockshaft is the fulcrum. A segment 34 is pivotally mounted upon the upper portion B of the typewriter frame and the said segment is rovided with a short-arm 35 which is linke to the forward arm of the lever or cross bar 33 by a connecting rod 36 so that when the shaft 30 is rocked the segment is actuated in relative pro ortion thereto. A pinion 37 is secured to t e rod or rock shaft 10 and meshes with the segment, as clearly shown in Fig. 1.

Theextreme rear end of the cross bar or lever 33 is provided with a mutilated segment 40 which is in constant mesh with a pinion 41 secured upon a rock shaft 42 disposed parallel with the rock shaft 30. A short arm 43 rojects from the shaft 42, and this arm is lin ed by a connecting wire 46to a lug or pin 45 which projects from the spacin do H as is clearly shown in Fig. 1 y

it in the L-shap'ed bracket 28 is a combined shifting and-locking device which has a cam 50, a curved top or hooklike locking portion 51 and guide pins 52, which guide pins bear in openings inthe bracketso that the cam has a vertical movement in the bracket 28. A shift key 54 is pivotally mounted in the lower portion of the type-writer frame at 53, and has an enlarged cupped out end 55 which is just beneath, and cooperates with, the lower end of one of the guide pins 52 which extends lower than the other or others, as clearly shown in Figs. 3 and 5.

In operating this tabulating device to bring a column or columns into vertical-alinement, the open column stops 20 are first placed upon the stop rod 12, by pushing them over the recess 14, and then movin each of them to the point u on the scale 1% where the decimal point w' appear in the respective printed column. The handles 24 are thenpulled downward so that the twin cams 23 enter the notches 13 oppositev the cams and lock the column stops securely inv position; the backs 25 which connect the two cams 23 impinging against the rod 12 prevent the cams from coming out of engagementwith the rod by the jarring of the machine.

s In 0 erating the machine we will now suppose t at it is desired to print the sum of 500.00 beneathan amount already printed; the shift key 54 is depressed and the cam 50, which is normallyheld downward by the spring 56, is thereby forced upward, releasing the locking portion 51 from engagement with the shaft and shifting the rock shaft 30' longitudinally toward the right and bringing the rockers 31 beneath the extensions 38 of the numbered -typewriter keys. The typewriter or rinting key bearing the numeral 5 whic key ordinarily is employed to print the numeral 5 is then depressed, the extension 38 on its lever bearing upon the rocker 31 beneath said lever, causing the rocker'to incline until the heel 31* touches the extension, thus preventing the lever from going further and arresting it at a point where the movement transmitted thereto is ineffective to throw the associated type bar to the printing point, thereby preventing an imprint ing key. It is at this time that the numeral prmtin keys may be used as tabulator eys. he dip thus imparted to the rocker moves the forward arm of the lever 33 downwardly and the segment 34 which is connected to the lever is moved, say a distance corresponding to four teeth of the segment. This movement is effective to turn the rock shaft 10 a corresponding distance or four-tenths of a revolution, thereby moving the denominational stops in a direction transverse to thetravel of the carriage, bringing the fourth spiral step or denominational stop 19 in line with the column sto ro'ection 21. A downward movement 0 the ore part of the lever '33 causes its rear end to rise a corresponding distance and the latter, hav-- ing the mutilated segment 40 secured there to moves the -mutilated pinion 41 until the untoothed portion of the segment 40 enga es the mutilated portion of the pinion 41. he slight turn which the pinion 41 makes is effective to tilt the short arm 43,'which is connected to the dog H, a distance sufiicientto pull down and to disengage the do H from the rack I. This disengagement o the dog from the rack releases the carriage which, by the tension of its main spring, is pulled forward'or' towards the left until the properly positioned spiral step or denominational stop 19 is brought into contact with the colby the actuation of the print-' umn stop projection 21, thus arresting the carriage to start writing 500.00. at the osition within the alreagdy prrinted. v e same operation is re: peat t ougho'utin the column 'orcelumns.

120. ressure on the shift a positions in the co umn.

Thus, when the typewriter or printing key bearing the numeral 2 is struck to brin the carriage to stop at the decimal point, an when the numeral key 3 is actuated it is 5 effective to stop the carriage at the units point and when the 4 key isactuated it arrests the carriage at'the tens point position and so on. The effect ofdepressing the different numeral keys when the shift key 54 is depressed is, as heretofore pointed out, to

turn the set of denominational stops 19 a distance corresponding to the denomination represented by the key depressed. As the pressure on the shift key is released the rock shaft 30 is forced to the left, thus carrying the members or projections 31 and'33 there on out of the path of the key extensions 38, and the numeral key levers. are thus allowed to play freely in the spaces between said projections.

- When the tabulator is inoperation and pressure upon the typewriter numeral key is released, the segment 34 which has been pulled forward against the tension of the spring 36 by the depression of the actuated key, is returned to its normal position, bringing the bare portion 18 between the terminal denominational stops in line with the projections 21 of the column stops, so that the graduated stop member 15 can pass the projections 21 freely without touching them. By spacing the adjacent denominational stops apart as shown the column stops may be received in the interdental spaces. between denominational stops as the latter are moved to and from o erative position, the stops passing one anot er freely in a vertical plane fore and aft of the machine or in a di rection, transverse to the travel of the car- 40 riage so that" column stops do not interfere with the free return of the denominational sto s to normal position. 0 reduce the jar which is caused by the released carriage striking against the col umn stops, at yielding cushion 15, which may be soft rubber or a spring, is interposed between the graduated contact piece 15 and the guide lugs F, as is clearly shown in Fig. 2.
